I reported an inconsistency in results in the same R program run on
different Windows computers and received some suggestions

It isn't due to the version of msvcrt.dll (Peter Dalgaard & Brian Ripley)
and isn't fixed by Duncan Murdoch's patches to windows R.

More experimentation has shown that the set of results I like less
(involving internal error reports from optim()) happens on 3 out of 3
Pentium 4 machines, and not on 2 Pentium 3s (or on a dual Athlon under
